To all 20700722, it may concern.-

' Be it known that 1, DAVID NEWTON GREEN, of Commercial Point, in the county of Pickaway and State of Ohio, have invented a new and useful Improvement in Grain-Binders, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1, Sheet 1, is a side elevation of my i mprovcnicnt, the shaft being shown in section. Fig. 2, Sheet 1, is a sectional elevation of the same. Fig. 3, Sheet 2, is a section of the same, taken through the line a: m, Fig. 1. Fig; 4, Sheet 2, is an elevation of the same. Fig. 5,

Sheet 2, is a sectional side elevation of the same, taken through the line y y, Fig. 4, parts being broken away and in section. Fig. 6, Sheet 2, is a sectional elevation of a part of the same, illustrating the grasping of the twine, part being broken away. Fig. 7, Sheet 2, is an elevation of a part of the same, illustrating the tying of the knot. Fig. 8, Sheet 2, is a view showing the completed knot and a section of the twine-grasper.

The object of this invention is to provide improved grain-binders designed especially for application to the Applcby grain-binding harvesters, but applicable to other grainbinding harvesters, and which shall be simple in construction and reliable in operation.

The invaition consists in the construction and arrangement of parts, as will be hereinafter fully described and claimed.

A is the cam and gear wheel, which is attached to the shaft B, driven from the driving mechanism of the harvester in the ordinary manner. The cam and gear wheel A is provided with a laterally-projecting rim, '0, having an inwardlyprojecting flange, D, upon its outer edge.

To the inner surface of the rim (3 is attached a section of geanteeth, E, into which mesh the teeth of the knotter-pinion F, and which are sufficient in number to revolve the knottershaft once for each revolution of the cam and gear wheel. The flange D of the cam and gear wheel A is designed to engage with a shoe, G, attached to or formed upon the knotter-shaft or the pinion F, to hold the said knottcrshaft from turning, and the flange is cut away opposite the gear-teeth E, to allow the said knottershaft to revolve when the pinion comes into engagement with the said gear-teeth E. The knotter-pinion F is attached to the shaft of the knotter H, which revolves in bearings in the frame I, through which the shaft B passes, and which frame is designed to be held stationary by an arm (not shown in the drawings) attached to a shoulder or flange, J, of the said frame I. The twine is guided to the knotter H by the curved cord guide and deflector K, the outer or notched end of which rests in a recess in the lower part of the frame I. The inner end of the cord guide and deflecting arm K has a small roller, L, pivoted to it, and rests in a groove, M, in the face of the cam and gear wheel A.

- In the side walls of the groove M is formed an offset or cam, N, which comes in contact with the roller L, and operates the cord guide and deflector K to bend the twine laterally over the knotter-jaws just before the knotter H begins to revolve. As soon as the ltnotter H has caught the twine the cord guide and deflector K moves back to its former position.

In the face of the cam and gear wheel A is formed a recess or depression, 0, to allow the movable cord-clamp P to be drawn back to release the twine.

To the side of the shank of the movable cord-clamp P is pivoted a small roller, Q, to roll along the face of the cam-wheel A. The movable cord-clamp P is drawn back to release the twine by the inclined projection or cam R, attached to or formed upon the outer wall of the groove M, and against which the roller Q of the said movable clamp strikes. As the roller Q passes out of the inclined end of the recess 0 the movable clamp P is pushed forward to again clamp the twine. The forward part of the movable clamp P is slotted to receive the stationary cord-holder plate or arm S, and has recesses T formed in its upper edge to receive the twine and press it against the edge of the said arm S. The inner part or prong of the movable clamp P passesbetween the cord-holder plate or arm S and the knife U, the-shank of which is secured to the cord-holder plate or arm S, with its edge a little above the lower edge of the said plate or arm S, so that the twine will be clamped before it is cut.

V is the movable jaw of the knotter, which passes through and is pivoted in a slot in the fixed jaw of the knotter H, and is closed at said cord guide and deflecting arm begins to move before the needle has completed its forward movement. As the knotter H begins to revolve and has turned part way, the movable jawVis opened by the projection X, and when the said knotter-hook has turned far enough to catch the twine held by the cord holder, consisting of the movable clamp and the stationary plate or arm, the movable jaw V closes upon the twine, and the knotter continues its revolution to its former position. When the movablejaw V of the knotter closes upon the twine, the movable clamp P opens and releases the twine previously 'held by it, and by the time the knotter H has completed its revolution the movable clamp P again clamps the new twine and presses it against the knife U and cuts it off. It will be observed that the cord-holder clamps the twine but once, and the knife cuts it off but once, and that the knot is stripped from the knotter by the discharge of the bundle from the binding-table by the arm B,attached to the cam and gear wheel A.

\ Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a grain-binder, the oombination,with the cam and gear wheel A, having a recess, 0, and projection R, of the knotter operated by said wheel, and the cord-holder eomprising the fixed plate S, at right angles to the axis of the cam and gear wheel, and the movable clamp P, at right angles to the plate S, and

provided with a notch, T, adjacent to the inner edge of the said plate S, substantially as set forth.

2. The combination, with the shaft B, the cam and gear wheel A thereon, and the frame I, of the knotter operated from the said wheel, 5 5 the movable cord-clamp P, operated from the cam and gear wheel, the said clamp being forked at its outer end and notched at T on the inner edge of said notched portion, and the stationary plate S, fixed to the frame I and extending through the forked end of the clamp P, substantially as set forth.

3. The combination of the frame I, the cam and gear wheel A, provided with the rim 0, inwardly-projecting flange D, and gear-teeth E, of the knotter H, the shaft of which is provided with a pinion, F, and shoe G within the flange D, the movable jaw V, pivoted to the knotter,the cam X, the cam NV, and spring XV, substantially as set forth.

4:. The combination of the cam and gear wheel A, having gear-teeth E, cam-groove M, and cam N on the inner wall of the groove facing the gear-teeth, and the knotter H V, the pinion I on the shaft thereof, and the cord guide and deflector K, pivoted to swing laterally, as shown, one end of the said guide resting in the cam-groove, and theother end having a notch at right angles to said guide, as shown, whereby the cam N will cause the cord guide and deflector to bend the twine laterally over the knotter-jaws just before the knotterpinion F is operated by the gear-teeth E to revolve the knotter, and the said cord-guide be returned to its normal position as soon as the knotter has caught the twine, substantially as set forth.

5. In a grain-binder, the combination, with the cam and gear wheel A, ofthe forked lIIOV- able clamp P, the fixed arm or plate S, at right 9 angles thereto and extending through the fork, and the knife U, fixed to the frame adjacent to the inner face of the inner prong of the forked clamp, substantially as set forth.
